Exploring Technology in Grade 11

What is the primary function of a microcontroller?

• To serve as a general-purpose computer processor.

• To store large amounts of data permanently.

• The primary function of a microcontroller is to control and manage specific tasks in embedded systems.

• To provide high-level programming capabilities.

Explain the difference between analog and digital signals.

• Analog signals are always digital in nature.

• Analog signals are represented in hexadecimal format.

• Analog signals are continuous and can take any value, while digital signals are discrete and represent data in binary form.

• Digital signals can take any value continuously.

What are the main components of a computer system?

• Graphics card, motherboard, power supply, and software

• Network cables, printers, speakers, and monitors

• The main components of a computer system are CPU, memory (RAM), storage, and input/output devices.

• Operating system, antivirus, web browser, and email client

Define the term 'network topology' and give examples.

• Network topology refers to the speed of data transmission.

• Examples of network topology include software and hardware.
